Évaluation(s)
N°	Nature	Coefficient	Objectifs
1	In this midterm, the students will be evaluated in the following topics: - Phase Transformation - Heat Treatment of Metals - Martensite Transformation - Tempering of Steel Alloys	0,3	Students will have a mid-term at the mid-course about the topics covered in the first half of the course.
2	The final exam tests the students’ understanding of the entire course, which includes: - Phase Transformation - Heat Treatment of Metals - Martensite Transformation - Tempering of Steel Alloys - Structural Hardening of Aluminum - Corrosion	0,45	At the end of the course, there will be a final exam about all the concepts covered in the course and the Laboratory sessions. The exam consists of short questions as well as thorough analysis problems.
3	The continuous assessment evaluates the students’ understanding after each session, which determines whether the goals of education are being met.	0,15	Students will perform a heat treatment for steel and aluminum alloys. They will also test the impact and resilience of each alloy. They will observe their microstructure. Students will also perform a corrosion test on some materials. Students will be graded on their performance and analysis of the LAB work.
4	Continuous Assessment	0,1	The students should expect a drop quiz in each session about the previous lesson. The students will be assigned to read research articles about several tribological systems and then, present the state of art. Students will be graded on their ability to analyze the topic as well as to correlate what they learned in the course to the research.
